In the highlands of Gaea lies a village of spellcasters known as Loch Wor, shrouded in mists and standing between the borders of an enchanted forest and a lake supposedly home to some dormant primordeal beast. Despite being relatively isolated, the village was fabled in legend for producing powerful mages, a reputation that has brought both good and ill fortune to its people. Many covet the power of magic, after all, and to them an entire settlement focused on this power is a most tempting prize.

In a village founded on mystic tradition, the birth of twins was seen as an omen of some sorts, although at the time no-one could agree just what it was foretelling. But as the twins Hocus and Pocus Thaum grew up without much incident, the portents were soon forgotten and as they reached adolescence their magical training began. Despite her lack of enthusiasm for anything, Hocus was found to have a natural aptitude for black magic, whilst putting aside his inability to assert himself Pocus seemed to take to white magic with relative ease. However, before they could advance much in the ways of sorcery, the portents finally came true as the Holy Knights came to Loch Wor, drawn by the tales of magical power hidden within. Wanting to keep this power for themselves, they quickly instilled martial law upon the village, and were it not for their parents' quick thinking the twins would have been imprisoned with the rest of the villagers. Fleeing from their home, all they could think about was the responsibility they had been burdened with, to learn the secrets of magic by themselves and grow powerful enough to liberate Loch Wor from the Holy Knights.

With nowhere else to turn to, the twins assumed they would need to travel far and wide to learn these secrets and thus ended up joining the crew of a ship who were searching for their lost captain. Initially the crew were a bit unenthusiastic about taking in two kids, but after Pocus cooked up the best meal they'd had for a long time and showed off his healing skills, he was taken in as both a cook and a medic. Meanwhile, since Pocus was unusually adamant about not leaving his sister behind, Hocus was allowed to join too under the provision that she actually at least tried to help cleaning up the place since she had a broom and all.
